Indonesian police have arrested a man suspected of owning the van that exploded outside a Bali nightclub last month killing more than 180 people.

The man was arrested in East Java, where he is being questioned, said East Java police chief Heru Susanto.

Police on Wednesday said they were questioning at least 10 people in connection with the Bali bombing, but no-one has formally been declared a suspect.

A man said to resemble a police sketch was arrested in Medan

Among the people arrested are two men said to resemble police sketches of men seen by several witnesses at the scene of the blasts.

However, it remains unclear whether police believe the two men were involved in the 12 October bombing.

One of the men was arrested in the North Sumatran capital of Medan on Monday after he was caught using fake identity papers, while a second man was arrested in Jakarta on Tuesday.

In addition to the people currently being questioned, nine others were questioned last week because they resembled the composite sketches of three suspects released last week by police. All were released without charges.
